CPD Session delivered by ILP Premier Corporate member WSP
Well-Managed Highway Infrastructure: a code of practice has been developed through consultation with practitioners, professionals and user groups. It was approved and published by the UKRLG in October 2016 and comes into force in October this year. The ILP are aligning TR22 to aid members in meeting the CoP but through regional workshops there seems to be a lack of awareness of the CoP’s existence. Allan will review and advise on the CoP which requires a step change in approach requiring an understanding of asset condition and a risk / asset management approach to the management of the asset.
